RVFM Rechargeable Solar Buggy

Designed for the purpose of investigating solar cells, this buggy includes a solar panel, a 0.22F super capacitor and a small circuit board for switching between 'charge' or 'run' modes.

In 'charge' mode the capacitor is charged up by the solar panel. In 'run' mode the solar panel is disconnected and the charge stored in the capacitor powers a motor that propels the buggy forwards.

• Experiments include:
• Charging the solar panel under different types of light source, e.g. tungsten, fluorescent, etc.
• Investigating distance travelled against charge time
• Exploring the effects of coloured filters with the solar panel
• Investigating the effect of charging at various distances from the light source
